Firstly you should check the cause of the issue by following below steps:
Open the command prompt. Enter “nslookup Google.com” without double quotes.
If you don’t get the IP address back, it is just your internet connection. If you are using wired connection check whether the cables are connected properly. If its wireless, try re-connecting it.
If you get the IP address back, then know “Virus or some other thing” is causing the issue.
I would suggest you to follow the below fixes to resolve this issue: Fix 1: Delete your cache and other browser data and check.
In the top-right corner of Chrome, click the Chrome menu.
Select More tools > Clear browsing data.
In the dialog that appears, select the checkboxes for the types of information that you want to remove.
Use the menu at the top to select the amount of data that you want to delete. Select beginning of time to delete everything.
Click Clear browsing data.
Fix 2: Clear cookies Whenever you visit a new website, it leaves a small piece of data called cookies with your web browser. When you visit the same website in future, this file will be used to remember who you are and what you saw in that website etc. You don’t really need to keep cookies from every website you visit. Every additional KB you add up with the “Temporary memory” will slow down your system. By default, Google chrome allows cookies from all website. So change the settings.
Open menu
Click “Settings->show advanced settings“
Expand the “Privacy Section” and Click “Content settings”
You will get the window as shown below
Change the settings as per your preferences and click on “All cookies and site data“.
This will show all the cookies and data stored in your browser. Click remove all -> done.
Fix 3: Close the non responsive window When you open more than one tab in Google chrome, chances are one or few tabs will get frozen. At times, closing only the non responsive tabs will fix the issue.
To do this open chrome’s task manager. You can do this by pressing the keys“Shift+Esc”
You will get a window showing all the running processes and extensions.
Choose the frozen tab or tabs and hit end process.
Fix 4: Fix Your Flash When working with Google chrome, almost all of us encounter the pop up, asking us to choose between “Wait / Kill pages”. It happens due to the conflict that occur between the Chrome’s internal Flash module and Adobe flash plug-in. When both are enabled, Instead of choosing any one, Chrome tries to use both and finally ends up with a browser crash. To avoid this issue, enable anyone of the flash version.
Enter the term “Chrome://plugins” in the chrome address bar without the quotes.
From the displayed plug-ins list, spot the plug-in “Adobe Flash Player”.
If adobe flash player is enabled, click disable (uncheck) it and close the chrome browser.
Re-launch the browser and check whether the issue is still exist.
When I connect an external microphone to the jack, it is not working. I can see it in the "Sound" tab, but the levels is very low. I have tried with several microphones.
